Closing of Service valve, crossing connection of refrigerant
piping and electrical wiring, proper operation of EEV (Electrical
Expansion Valve) can be checked automatically in cooling
operation. This check operation can be done at 0~43ºC outdoor
temperature and 10~32ºC indoor temperature by use of
outdoor unit dip switch. The check should be done in one
refrigerant system. It takes 15~30 minutes and avoids frequent
failure by preventing careless mistakes during installation.

3 Layer Construction
(KX6 , KXR6 )
Thanks to improvement of

4 to 3 layer construction
and by use of hinged lays,
service and maintenance
has been made much easier
for inverter components.
Back-up Operation
In, 2-compressor module, in the event of the compressor
failure, the system will keep operating with good compressor.
In combined module, in the event that one unit has a failure,
the system will keep operating with another unit.
Should compressor be damaged, compressor replacement
should be done as soon as possible. However as emergency
measure for a limited time, in 2 compressor module, the
system can be kept operating with the good compressor. In
combined module, the system can be kept operating with the
other unit.

heat pump systems
KX6 heat pump systems operate with 2 inter-connecting pipes,
thus commonly referred to as a '2-pipe system'.
These systems provide either a heating or cooling operation to all
indoor units and are suitable for a wide range of applications from
an individual apartment (with "Micro KX", 1/phase system) to an
entire multi storey building, especially where there are significant
open plan areas to be controlled.
The range starts with a 11.2kW cooling capacity, up to the largest
capacity single outdoor unit in the industry (24hp) with 68.0kW
cooling capacity. Outdoor units can also be “twinned” providing up
to 48HP/136.0kW on a single system.
The KX6 range has a total piping length of 1000m (14HP+) and the
furthest indoor unit can be connected up to 160m (8HP+) from the
outdoor unit.
Fixed Cooling mode/fixed heating mode (summer/winter switch):
It is possible to fix the operational mode of the system (either cooling or heating) using a switch (SW3-7) on the outdoor
unit PC board - this enables the building user to decide the operation of the system (e.g. cooling only in summer/heating
only in winter), to avoid unnecessary energy wastage. It is also possible to wire the control switch to a remote location
(inside the building) to a control room, or even linked to an ambient thermostat.

refrigerant piping
Installation of Interconnecting Pipework
Mitsubishi KX6 equipment is manufactured to
the highest standards of quality and reliability.
It is imperative the method of installation and
the materials used are also to high standards,
to ensure trouble free operation and long term
reliability.
The interconnecting pipework must be installed
by a competent and trained engineer.
Refrigeration quality copper tube must be used,
soft copper coils or half-hard straight lengths.
The refrigeration quality tube must be soft
drawn seamless high grade copper pipe. The
copper tube must be selected taking into
account the higher operating pressures of
R410A refrigerant, and that high pressures will
occur throughout the system because of the
reverse cycle operation. All pipework material
used should be EN12735 European standard.
The supplied branch pipe kits, must be used
to make connections to indoor units, and the
supplied manifold kits must be used to make
connections between outdoor units (where
applicable); it is not permitted to use standard
fittings such as elbows, tees etc. The branch
pipes shall be installed in accordance with the
manufacturer’s instructions, allowing
unrestricted flow of refrigerant, and in
accordance with European standard E378:2000.
All brazed joints shall be made with dry
nitrogen purge to ensure the prevention of
oxidisation to the internal surface of the copper
pipes.
The ingress of moisture, dirt and any other
contaminants to the interior of the copper
pipes, and air conditioning units, must be
prevented during the installation procedure.
After the installation of pipework, prior to the
connection of the outdoor units, and sealing of
insulation joints, the pipework must be
pressure tested for leakage, using dry nitrogen.
Additional Refrigerant
Additional R410A refrigerant only shall be used,
and must be charged by weight only, using
electronic scales. The amount of additional
refrigerant must be accurately calculated from
the manufacturerís data, based on the length
and diameter of each section of the liquid
refrigerant pipework of the system.

heat recovery systems - for simultaneous
heating and cooling
KXR6 heat recovery systems operate with 3 inter-connecting pipes,
thus commonly referred to as a '3-pipe system'.
where the building orientation (N, S, E, W) can mean that heat gain/loss
varies on each side of the building.
KXR6 systems provide both heating and cooling operations to individual
indoor units according to the room condition/requirement.
KXR6 incorporates highly sophisticated control to condition multiple indoor
areas, whatever their requirement for cooling or heating, for applications
The range starts from the 8hp model (22.4kW) cooling capacity, up to the
largest capacity single outdoor unit in the industry (24hp) with 68.0kW
cooling capacity. Outdoor units can also be “twinned” providing up to
48HP/136.0kW on a single system.

KXR6 heat recovery systems - for simultaneous heating and cooling
The KXR6 system interconnecting pipework has a unique arrangement, with two of the interconnecting pipes routed through a
PFD Distribution Controller, and the third pipe connected directly to each indoor unit from the main pipe run. This reduces
installation time, and the number of brazed connections on site. The PFD Distribution Controllers are available for single
connection, or as a combined PFD 4-way connection, with each connected unit having independent cooling or heating operation.
Cooling and heating balanced operation
During defrosting or during automatic protection of a compressor, which is activated every several hours in heating operation, heating operation temporarily
stops and restarts after some period. KXR6 series has the same automatic protection of compressor in cooling operation also. During this protection period air
flow only comes on and cooling operation restarts after some period.
This model is not suitable for the usage of annual cooling operation such as for the server room, especially in the area where the outdoor air temperature
becomes below 5ºC. In case of mixed opeartion in cooling and heating mode below 5ºC of outdoor air temperature, the cooling capacity may decrease in
comparison with that for the operation only in cooling mode.

•In case of the mode changeover from cooling to heating and from cooling
to heating, by the use of only the indoor units and PFD box combination,
the mode changeover sound was reduced. All this made possible without
turning off the compressor and at the same time without the reduction of
capacity.
•The risk of refrigerant leakage was reduced by changing piping connection
at the PFD box to brazing method.
•By the use of optional PFD box
extension cable that has a connector
at ends, makes it possible to further
separate the indoor unit and PFD
box. This will enable the PFD box to
be located away from the indoor
unit and help reduce the influence of
sound caused by PFD box and
refrigerant flow.

Installation of Interconnecting Pipework
Mitsubishi KXR6 equipment is manufactured to
the highest standards of quality and reliability.
It is imperative the method of installation and
the materials used are also to high standards,
to ensure trouble free operation and long term
reliability.
The interconnecting pipework must be installed
by a competent and trained engineer.
Refrigeration quality copper tube must be used,
soft copper coils or half-hard straight lengths.
The refrigeration quality tube must be soft
drawn seamless high grade copper pipe. The
copper tube must be selected taking into
account the higher operating pressures of
R410A refrigerant, and that high pressures will
occur throughout the system because of the
reverse cycle operation. All pipework material
used should be EN12735 European standard.
The supplied branch pipe kits, must be used
to make connections to indoor units, and the
supplied manifold kits must be used to make
connections between outdoor units (where
applicable); it is not permitted to use standard
fittings such as elbows, tees etc. The branch
pipes shall be installed in accordance with the
manufacturer’s instructions, allowing
unrestricted flow of refrigerant, and in
accordance with European standard E378:2000.
All brazed joints shall be made with dry
nitrogen purge to ensure the prevention of
oxidisation to the internal surface of the copper
pipes.
The ingress of moisture, dirt and any other
contaminants to the interior of the copper
pipes, and air conditioning units, must be
prevented during the installation procedure.
After the installation of pipework, prior to the
connection of the outdoor units, and sealing of
insulation joints, the pipework must be
pressure tested for leakage, using dry nitrogen.
Additional Refrigerant
Additional R410A refrigerant only shall be used,
and must be charged by weight only, using
electronic scales. The amount of additional
refrigerant must be accurately calculated from
the manufacturerís data, based on the length
and diameter of each section of the liquid
refrigerant pipework of the system.

(1) This unit is the specific unit for processing the outdoor air temperature closer to the room temperature. For conditioning the room temperature a
dedicated air-conditioner is required additionally.
(2) This unit monitors the outdoor air temperature and controls thermostat ON/OFF at the setting temperature by the remote controller, which
indicates the outdoor air temperature for controlling thermostat ON/OFF. When thermostat is turned OFF, the operation is changed to the fan mode
so that unprocessed outdoor air will be blown into the room directly. Therefore place the air outlet port or orient the air outlet direction not to blow
air directly to persons in the room, especially in the small room such as a restroom and/or sanitary hot water supplying room.
(3) It is strictly prohibited to monitor the room temperature by switching to the thermistor at remote controller side and/or the optional remote
thermistor. Otherwise dew formation at air outlet port and/or dew dripping may occur during cooling operation due to the lower outdoor air
temperature. Therefore keep the remote controller of this unit in place closer to the administrator so as not to be touched it freely by the end user.
(4) Dehumidifying operation with this unit is prohibited.
(5) When handing over this unit to the end user, make sure to explain sufficiently about the foregoing cautions, the installation place and usage of
remote control for this unit and the location of the air outlet.

Concept (Difference between FDU-F and SAF)
SAF is the energy recovery ventilation unit which can recover heat energy from exhaust air to supply air and "has no air processing
function, but FDU-F is air processing unit which can treat the supply air closer to room temperature by cooling or heating in connection
with KX6 refrigerant system and exhaust air is discharged to outside of the room.

1. The data are measured at 33ºCDB 28ºCWB (68%RH) during cooling and 0ºCDB-2.9ºCWB (50%RH) during heating (no frost). External static pressure of indoor unit with optional fan controlling kit "U-FCRB" is 100Pa.
2. Temperature range of outdoor air must be 20~40ºCDB (32ºCWB) during cooling and -10~24ºCDB during heating.
3. Operation sound is measured in an anechoic room based on JIS standard. In case of actual room installation, it usually becomes higher than the displayed value due to the surrounding noise and echo.
4. The total connection capacity of the other standard air conditioning units and the outdoor air processing units must be from 50% to 100% (the total includes the outdoor air processing unit). The connection capacity
of the outdoor air processing unit must not exceed 30% of the capacity of the outdoor unit.
5. Single outdoor air processing unit can be used alone. The connection capacity of the outdoor air processing unit must be from 50% to 100% of the total capacity of the outdoor unit.
6. Single outdoor air processing unit can be used alone. Maximum number of outdoor air processing units that can be connected to the outdoor unit is 2units.
7. Values of sound pressure level become increased 5dB(A), when external static pressure is 200Pa (factory setting).
8. Values of air flow volume are those at external static pressure 200Pa (factory setting).

Re; Building Regulations Part L2
The Part L2 (April 2006) regulations limit the amount of electrical/gas
power to be used to provide heating or cooling in commercial
buildings. Therefore the building designer needs to select energy
efficient heating/cooling equipment, and to minimise energy losses
through ventilation systems.
The SAF recovers heat energy which would otherwise be exhausted
to atmosphere, and uses this energy to warm the air entering the
building. The reverse happens in warmer climates, where the
exhausted cool air is used to partially cool the incoming air.
Capturing this waste energy, means the heating/
cooling requirements of the building are reduced, so
smaller size plant can be selected, savings can be
made in long term energy consumption, and carbon
emissions are reduced.
The inclusion of the SAF energy recovery ventilation
units in the building design, will reduce the total
amount of carbon emissions.

Room temperature controlled by the remote control sensor
The temperature sensor is housed in the top
section of the remote control unit. This arrangement
has improved the sensitivity of the remote control
unit’s sensor, which permits more finely
controlled air conditioning.
Weekly timer function as standard
RC-E5 provides (as a standard feature) a weekly timer, which
allows one-week operation schedules to be registered. A user can
specify up to four times a day to start/stop the air conditioner.
(Temperature setting is also possible with the timer).
Changeable set temperature ranges
RC-E5 allows the upper and lower limits of a set temperature range
to be specified separately.
By adjusting a set temperature range, you can ensure energy saving
air conditioning by avoiding excessive cooling or heating.

Service/maintenance and monitoring
The design of the outdoor units separates the air flow compartment from
the mechanical compartment, allowing easy access to serviceable parts
by simply removing the panel.
Air flow chamber
This design also means that the base plate of the air flow compartment
acts as a drain tray connected to a drain pipe that runs through the
mechanical compartment, so a simple connection of a drain hose to the
base of the unit is all that is required, no need for a separate drain tray to
be installed.
Mechanical
chamber
Service maintenance and trouble shooting tasks can be carried out easily
via the wired remote controller, as well as a cooling test operation to
assist commissioning.
The outdoor unit control box is also equipped with a switch to invoke a
'test-run' mode. This function can be used to help detect any installation
errors, indoor/outdoor unit matching errors, EEV and valve operation. A
'pump-down' switch on the PCB allows refrigerant to be recovered with
the compressor protected.
All outdoor unit PCBs are also equipped with a 7-segment digital display
for detailed operation history and fault finding. Operation data is stored
for the 30 minute period preceding a fault occurring and details are
displayed on the 7-segment reading.

Mitsubishi Heavy Industries
Mitsubishi Heavy Industries operates a continuous CSR (Corporate Social Responsibility) policy, with a role to realise a sustainable society through it’s
various areas of business.
Creed
•

•
We strongly believe that the customer comes first and that we are obliged to be an innovative partner to society.
We base our activities on honesty, harmony, and a clear distinction between public and private life.
We shall strive for innovative management and technological development from an international perspective.
/further information
Reason for Instituting the Creed
In Japan there are many enterprises with their own “creeds” which simply represent their management
concept.
Mitsubishi Heavy Industries, Ltd. has a creed of this type, also. It was instituted in 1970 on the basis of
the policy advocated by Koyata Iwasaki, president of Mitsubishi Goshi Kaisha in the 1920’s, to indicate
the essential attitude of the company, the mental attitude of the employees, and the future directions of
the company.
The reason for instituting the present creed is so that all of us can call to mind our one hundred years of
tradition, and strive for further development in the future.

The KX6 product range has been developed in compliance with the Mitsubishi Heavy Industries Policy on the Environment.
In order to make the sustainable development of society possible, a basic policy on environmental matters has been established.
Pursuant to the express provision of Section 1 of its creed that “We strongly believe that customers come first and that we are obligated to be an
innovative partner to society,” MHI shall, as a matter of primary importance, strive, through its R&D, manufacturing and other business activities, to play
a useful role in the development of society. To this end, while remaining aware that a business enterprise is a member of society, MHI shall endeavour,
in all aspects of its business activities, to reduce the burden on the environment and shall concentrate and fully utilise its technological capabilities for
the development of technologies and products that will protect the environment, thus contributing to the establishment of a society in which sustainable
development is possible.
In order to realise its basic policy, MHI has set the following seven conduct guidelines.
1. Recognise that environmental protection is top priority in the companyís operations, and encourage the entire company in its endeavours to protect and
improve the environment.
2. Define roles and responsibilities regarding environmental protection by developing and maintaining a corporate organisation designated for environmental
protection, and create and implement corporate policies and procedures on environmental matters.
3. Endeavour to reduce the burden on the environment by preventing pollution, saving resources, saving energy, reducing waste, reusing materials, and recycling
in all aspects of the companyís business activities in R&D, designing, procurement of materials, manufacturing, transportation, use, service and disposal.
4. Endeavour to develop and provide advanced, highly reliable, unique technologies and products that contribute to solving environmental and energy problems.
5. Comply with national and local environmental laws and regulations, beyond mere compliance by enacting, implementing and evaluating voluntary
standards where necessary, and to endeavour to continuously improve and promote environmental protection activities by establishing environmental
goals and targets.
6. Endeavour to protect the environments of foreign countries by carefully examining the consequences of the companyís overseas business operations and
the exportation of its products, and to become actively involved in technological co-operation overseas in areas of environmental protection.
7. Provide environmental training and other programs to enhance the environmental awareness of all company employees, and take steps to expand public
relations activities, such as providing environment-related information to the public and social contribution activities.

Before starting use
Heating performance
The heating performance values (kW) described in catalog are the values
obtained by operating at an outdoor temperature of 7C and indoor
temperature of 20 C as set forth in the ISO Standards. As the heating
performance decreases as the outdoor temperature drops, if the outdoor
temperature is too low and the heating performance is insufficient, use other
heating appliances as well.
Indication of sound values
The sound values are the values (A scale) measured in a chamber such as an
anechoic chamber following the ISO Standards. In the actual installation
state, the value is normally larger than the values given in the catalog due to
the effect of surrounding noise and echo. Take this into consideration when
installing.
Use in oil atmosphere
Avoid installing this unit in as atmosphere where oil scatters or builds up,
such as in a kitchen or machine factory.
If the oil adheres to the heat exchanger, the heat exchanging performance
will drop, mist may be generated, and the synthetic resin parts may deform
and break.
Use in acidic or alkaline atmosphere
If this unit is used in acidic atmosphere such as hot spring areas having high
level of sulfuric gases or in alkaline atmosphere including ammonia or
calcium chloride, places where the exhaust of the heat exchanger is sucked
in, or at coastal areas where the unit is subject to salt breezes, the outer plate
or heat exchanger, etc., will corrode. Please ask a dealer or specialist when
you use an air conditioner in places differing from a general atmosphere.
Use in places with high ceilings
If the ceiling is high, install a circulator to improve the heat and air flow
distribution when heating.
Refrigerant leakage
The refrigerant (R410A) used for Air conditioner is non-toxic and
inflammable in its original state.
However, in consideration of a state where the refrigerant leaks into the
room, measures against refrigerant leaks must be taken in small rooms
where the tolerable level could be exceeded. Take measures by installing
ventilation devices, etc.
Use in snowy areas
Take the following measures when installing the outdoor unit in snowy areas.
·Snow prevention
Install a snow-prevention hood so that the snow does not obstruct the air
intake port or enter and freeze in the outdoor unit.
·Snow piling
In areas with heavy snow fall, the piled snow could block the air intake
port. In this case, a frame that is 50cm or higher than the estimated snow
fall must be installed underneath the outdoor unit.
Automatic defrosting device
If the temperature is low, and the humidity is high, frost will stick to the
heat exchanger of the outdoor unit. If use is continued, the heating
performance will drop.
The "Automatic defrosting device" will function to remove this frost.
After heating for approx, three to ten minutes, it will stop, and the frost will
be removed. After defrosting, hot air will be blown again.
Servicing the air-conditioner
After the air-conditioner is used for several seasons, dirt will build up in
the air-conditioner causing the performance to drop. In addition to regular
servicing, we recommend the maintenance contract (charged for) by a
specialist.
Safety Precautions
Air-conditioner usage target
The air-conditioner described in this catalog is a dedicated cooling/heating
device for human use.
Do not use it for special applications such as the storage of foodstuffs,
animals or plants, precision devices or valuable art, etc.
This could cause the quality of the items to drop, etc.
Do not use this for cooling vehicles or ships. Water leakage or current leaks
could occur.
Before use
Always read the "User , s Manual" thoroughly before starting use.
Installation
Always commission the installation to a dealer or specialist. Improper
installation will lead to water leakage, electric shocks and fires.
Make sure that the outdoor unit is stable in installation. Fix the unit to
stable base.
Usage place
Do not install in places where combustible gas could leak or where there
are sparks.
Installation in a place where combustible gas could be generated, flow or
accumulate, or places containing carbon fibers could lead to fires.
